<p><strong>BLUE-CNC (nema23) Version 1.0</strong></p> https://youtu.be/gL4MpC-D_eI <p>Like many others, I was interested in building a 3D printed cnc, in fact I opted for the TopsCNC (https://www.thingiverse.com/thing:3813481)</p> <p>But after starting the construction of the TopsCNC I thought that a mechanic based on Nema 17 motors might not be enough, so I decided to adapt the design to some Nema 23 motors, when I realized I had already modified 60% of the design, that's when I launched to completely modify the previous design.</p> <p>The particularity of the design is a DIY CNC, which mounts Nema 23 motors, being aware that this increases the price of the design, I decided to save part of the budget, installing the entire system with GT2 belts instead of screws.</p> <p>The electronics part is built by an arduino UNO and a Cnc Shield, with TB6560 drivers.</p> <p>In my case, use 1000mm aluminum profiles, and the working area I can get is 850mmx850mm.</p> <p>Actual budget</p> <p>In 3d filament 1.8 kg would be necessary, in my case it was Petg for the most part, it can also be made in PLA.</p> <p>Petg € 24 / kg = € 45</p> <p>PLA € 19 7kg = € 36</p> <p>In necessary materials we have 330 € with milling machine included</p> <p><strong>The economic cost would be around 370 €.</strong></p> <p><strong>Listing necessary things</strong></p> <p><strong>Screws:</strong></p> <p>22u - Wooden screws <strong>(depends on the base you use)</strong></p> <p>22u - M5x50</p> <p>12u - M4 x25</p> <p>8u - M6x30</p> <p>8u - M4x10</p> <p>30u - M4x15</p> <p>8u - M4x30</p> <p>2u - M4x25</p> <p>24u - M6 nuts <strong>(wheel spacers)</strong></p> <p>6u - M5x35</p> <p>32u - Nut for slot 5 type-I [M4]</p> <p><strong>Components:</strong></p> <p>4u - V-Slot 20x40mm- 1000mm</p> <p>1u - Closed GT2 Belt 280mm 140 teeth</p> <p>3u - GT2 20 teeth pulley 8mm axle</p> <p>2u - SC8UU linear bearings</p> <p>1u - RPTS trapezoidal threaded spindle right TR 8x1,5</p> <p>1u - Trapezoidal spindle nut - flange EBFM 8x1,5</p> <p>8u - Bearings 608 2RS 8x22x7mm</p> <p>1u - Precision steel shaft Ø8mm 1000mm</p> <p>2u - Precision steel shaft Ø8mm 180mm</p> <p>1u - Closed GT2 Belt 200 mm 100 teeth</p> <p>4u - GT2 Pulley 40 teeth 8mm Shaft 2 Units</p> <p>1u - 3D Timing Belt, GT2-6mm 10M</p> <p>3u - 2GT timing belt aluminum gear clamp mounting block</p> <p>1u - CNC Shield V3.0 + R3 Board</p> <p>1u - 10pcs 3D Printer V-slot Pulleys POM Plastic V Wheel V-slot Pulley</p> <p>1u - KATSU 101750 Electric</p> <p>1u - 4 pcs TB6560 stepper motor controller + interface board + 4 pcs Nema23 270 Oz-in motor + power supply</p>
